Students share their experiences of "placement poverty", which is when mandatory, unpaid placements push them into financial stress and sometimes out of their studies.
Literally every uni in Australia requires it, but not for every degree. Teaching and medicine are the two that come immediately to mind for me. From the article, it seems like social work also requires a sort of prac.
Engineering, at least at UQ where I did my degree, requires you do 60 days of work, but there's generally an expectation that you will be paid during that work. You're doing that work for private companies finding places yourself, so they kind of have to treat you as a normal intern (which in Australia, means being paid). It's different from the placements that the uni themselves organise with government departments like happens in medicine and education.
Interesting... I studied software development at Swinburne (2008-2011) and every student in the course did a one year work placement in year 3. It was paid about 3/4 the salary of a graduate job.
